I got my Giant withouta kickstand because all the biking books said you just lean the bike and that kickstands added weight.
Two days later I went back and had 'em put on a kickstand. ONe difference is that Giant is heavy - my Aluminum bike I can lean and it doesn't fall. The Giant, even w/o the Xtra, is just too heavy and I take it too many places. Super speed is *not* my agenda.
(One design issue with the Xtra *is* that it falls over easily with a regular kickstand, so I have a "rock sturdy" for making those smoothies. However, I'd like even better a true "kickstand" that I didn't have to actually stick into the bicycle, and I wish I'd known that before I got the rock sturdy.)
The paint issue - welp, could rust be an issue? That would be the only thing I'd worry about.
